Kind of depends and changes depending on a lot of factors, to be honest.

When I worked in an office, I discovered that headphones + music was the key to productivity for me. When I transitioned to work at home and had a more or less quiet home office to work in, I found that having music going was a bit irritating at times and totally not helpful at the best.

So I guess the deciding factor is whether I have to deal with the ridiculous noises other people make or not?
